hpplication filed October 14, 1907. Serial No. 397,423;

To all whom it may concern:

Be it known that l, Gnonen WASHINGTON SHARP, a citizen of the United States, residing at Baum, in the county of Chickasaw,

I hly invention relates to new and useful improvements in combined cotton choppers and. cultivators and my object isto provldemeans in connection with the cultivator for removing portions of the growing plants.

A, further ob3ect 18 to provide means for intermittently moving the chopping blade ends of which are securedshov across the row of growing plants.

A still further object is to provide means for 'elevating the blade above the row of plants on its return stroke, and a stillfurther object is to provide means for operating the chopping blade.

Other objects and advantages. will be hereinafter referred to and more particularly pointed out in the claims.

in the accompanying drawings which are made a part of this application, Figure 1 is a top plan view of my improved cotton chopper and cultivator l ig. 2 is a sectional view as seen on line Fig. 1. Fig. 3 is a sectional view as seen. on line :3-3, Fig. 1, and, Fig. 4 is a bottom plan view of the chopping blade and parts supporting the same.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates a frame, which maybe of the usual. or any preferred. form, said frame being secured to an axle 2, to the opposite ends of which are secured supporting wheels 3 and 4.

.Pivotally secured to the side bars of the frame 1 are beams 5, said beams extending rearw ardly and over the rear barof the frame 1 and have secured thereto depending shank 6, to the lower end of which are secured the usual or any preferred form of cultivator shovels 7, by which meansgglthe soil between the rows of growing plants is cultivated. The forward end of the frame 1 is also provided with depending shanks 8 to the lower means the soil adjacent the growing plants'is cultivated.

' In order to remove superfluous plants from the row and leave the'growing plan-ts substantially an equal distance apart, I'provide my improved form of chopping blade 10, the rear edge and ends of which are provided with upwardly extending flanges 11, while to the rear flange is secured a socket 12, to receive the lower-end of an operating arm 13, saidsocket being removably secured tothe arm by providing an elongated slot lflin'the socket 12 and introducing a pin 15 through the slot and into the arm 13, thereby removably securing the blade to the arm and in such manner as to allow swinging motion thereof on the arm.

the frame 1,. and in osition to receive at its forward end, the ax e 2, is a bar 16, said bar extending a distance above the axle 2 and has secured to its forward end, a stub shaft 17, on the rear end of which is mounted the arm 13, said arm being provided with a longitudinally disposed slot 18, though which the stub shaft 7 enters and the arm is held in position on the shaft by means of a nut 19, or in any other preferred manner.

In order to swing the arm laterallyacross the row of growing below the slot 18 is provided with a lug 20, with which is adapted to engage a )lurality of auxiliary lugs 21 on the outer ace of a disk 22, the meeting faces of said lugs bein be reduced when the arm 13 is being operated by the disk. The disk 22 is rotatably mounted on the stub shaft 17 and between the end of the bar 16 and. the arm 13 and has fixed thereto a bevel pinion 23, which meshes with a driving pinion 24 on the axle 2, and it will be seen that as the axle 2 rotates, the disk 22 will be likewise rotated and the lugs the lug ,20 on the arm 13 and the. lugs on the disk and the lug on the arm are so situated, that the-' blade at the lower end of the arm the left of the ro'w of growing plants and certain distance to-the left, the lug 20'will :1 3 hile,

Lmove ou uof the path of the lug 21,"iwith curved, so that the friction therebetween wi 21 successively moved into engagement with will be moved a distance to one side or'to- Extending forwardly fromjhe rear bar of' plants as the cultivator is moving forwardly, that portion of the arm 13 when the lower end of the arm has moved a v which it is engaged, whereu the arm 13, will quickly swing the armton the stub-shaft '17 thespring 25 lug 21, whe

' cause the cho may be readily turned mountin tric to the stub-shaft 17,

arm is swung to direct the blade through the" will positively o fl'uous number o the growing plants, and it and move the cuttingblade 10 through the row of growingplants and to the opposite side.

of the row, the opposite end'of the spring 25 being adjustably secured to a standard 26 on the frame 1, by securing the spring to abolt 26*, which bolt is adapted to be introduced through openings 26 in I the .standard, whereby the tension of the spring may be in creased or decreased, as desired.

- Extending from side to side of the frame 1 and in front of the arm 13, is a guide 27, the central portion of which is curved downwardly to form a' circular lug 28 onthe arm 13, the upper, curved surface of the guide 27 being eccenso. that when the row of plants, the arm' will ,be moved u wardly the full length of the slot 18, therebysupporting the blade above the row ofgrowing plants and directly in the path of the next succeeding auxiliary lug, the tension of holding the arm in its elevated position, until the arm has made its return stroke, when the pressure on the lug 20 by the auxiliary lug'21 will again lower'the arm 13 until thelug 20 passes below the auxiliary n the spring 25 will again swing the blade across the row of growing plants.

In order to allow the blade 10 to partially rotate on the arm 13, as when one end thereof engages a solid object, and, atthe same time, normally hold the blade in its operativ'eposition, a spring 29 is secured to the lower end of the arm 1-3 and below the socket 12, the

ends of the spring being curved inwardly and adapted to rest against the flange 11 at the rear edge of the blade, said s ring being secured to the arm in any suita le manner, as by directingabolt 30 through the spring and into the arm. I In order to positively drive the axleZand 1n wheel 3 is fixe tb t e shaft 2 in any suitable manner, while the wheel 4 is rotatably mounted on .the shaft, so that the cultivator The arm 13 when moved across the row of plants is brought violently into engagement with a stop 31 on the curved face of the guide 27 the impact throwing the dirt from the blade 10;

It will thus be seen that I-have provided a very cheap and economical form'of com bined cultivator and chopper and one that erate to'remove a superwill further be seen that by yieldinglv the blade as shown and described, said bla e will not become broken when track-way for a semi-' ing pimons on said disk at the upper end of-the arm to device to I operate, the
